Problems solved by technology

[0005] The application scenarios of the existing GB28181 protocol make it impossible for the public security platform to monitor network devices other than the public security platform at any time through the external network, so it is impossible to conduct timely emergency dispatch based on real-time images
The existing SIP4G wireless streaming solution, the traffic from RTP data packets to cloud data is large, and the delay of real-time video is high, which greatly reduces the user experience

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 In the described embodiment, the SIP protocol Internet monitoring method under GB28181 specifically comprises the steps:

[0027] (1) The IPC starts the GB28181 module, and according to the set SIP_SVR, device id and port number, forms a SIP registration package and registers with the SIP_SVR central server;

[0028] (2) After the SIP_SVR central server is started, it monitors the configured IP and port. When receiving the SIP registration packet, it judges whether the authentication header is empty; if it is empty, returns a random number to the requested device and enters the next step; if not If it is empty, verify whether the username and password are correct; if it is correct, enter step (4), if it fails, return 401 authentication failure;

[0029] (3) IPC receives a 401 authentication failure error, and then obta...

Abstract

The invention discloses an Internet monitoring method under the SIP protocol under GB28181. It mainly corresponds to the access of security equipment through the external network through wireless 4G or wifi modules, and the access of individual equipment through wireless or wired methods; combined with the sip protocol, it is registered to the corresponding sip server at the remote end of the Internet, and the sip server controls the information The command interaction will control the 4G camera to interact with the individual device; the 4G camera will push the corresponding RTP data packet to the individual device through the cloud multimedia server, and transcode it through the decoding module, and provide it to multiple external network clients for monitoring through rtmp . The beneficial effects of the present invention are: access to the Internet through 4G dial-up mode or wifi wireless mode, combined with the sip protocol, centralized management and control of devices at different physical locations and real-time stream playback, so that managers can manage and control devices in time; for emergency scenarios, real-time to schedule.

Description

technical field [0001] The invention relates to the technical field related to security video, in particular to an Internet monitoring method under the SIP protocol under GB28181. Background technique [0002] GB28181 "Technical Requirements for Information Transmission, Exchange, and Control of Security Video Surveillance Networking System" was proposed by the Science and Technology Information Bureau of the Ministry of Public Security, under the jurisdiction of the National Security Alarm System Standardization Technical Committee (SAC / TC100), and the No. 1 Institute of the Ministry of Public Security, etc. A national standard jointly drafted by the unit. [0003] This standard stipulates the interconnection structure and communication protocol structure of information transmission, exchange and control in the urban monitoring and alarm network system, the basic requirements and security requirements for transmission, exchange and control, as well as the technical requirem...
